Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed September'20, 1909. Serial No. 518,483.

Ulm, in the county of Brown and State of Minnesota, have invented certain new and useful Improvements in Carrier Systems; and I do hereby declare the following to be a full, clear, and exact description of-the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to carrier systems, and has for its especial object to provide an improved transfer mechanism for transferring parcels from one carrier to another, which runs-at an angle thereto.

To the aboveends, the inventionconsists of the novel devices and combinations of devices hereinafter described and defined in the claims. i

This improved transfer mechanism is es pecially adapted for use in connection with carrier systems wherein there is a main or primary carrier, and one or more branch or secondary carriers running approximately at a right angle thereto, and Where the said carriers are made up of laterally spaced endless carrier belts-or cables and cooperating guiding and driving wheels. Carrier-systems of this character are capable of a very wide range of use, and they are found very serviceable, for example in brickyards, for the purpose of conveying pallet boards load: ed with bricksfrom the press along the main or primary carrier to one or the'other of the several branch 'or secondary carriers, by which latter the loaded pallet boards are carried to suitable places of deposit.

In the accompanying drawings which illus- 40 trate the invention, like characters .indicate like parts throughout the several views.

Referrmg to the drawings: Figure 1 is a plan view showing the improved transfer mechanism; Fig. 2 is aside elevation of the transfer mechanism,- some parts being broken away and some parts being removed Fig. 3 is a detail in transverse vertical section, taken approximately on the line 00 m3 of Fig. 1; Fig. 4 is a detail. partlyin elevation and l partly in section on the line m w of Fig. 1,

some parts being brokenaway; and Fig.

is a detail in section, taken-- on the line m m of Fig. 2. I

' pro er Of the-parts of the carrier system the numeral l'indicates the parallel run over suitable p rimary carrier, which guldlng ordriving wheels cables of the main or or sheaves, shown in Fig. 2, and is indicate by the nu meral 2.

The numeral 3 indicates the endless cables or belts of the secondary or-branch carriers, which as shown, run at right angles to the cables 1, and .over suitable driving and guiding sheaves 4:, several of which are shown diagrammatically in Fi 1.

Pallet boards 5, see Flgs. 2 and 5-, adapted to support bricks 6, are provided at their 'ends with *depending flanges 7, and are adapted to be placed loosely upon the upper horizontally ext-ended portions of the carrier-cables 1, and to be carried to or past any of the secondary or branch carriers 3. My

improved mechanism, which will now be described,'is portable, and is adapted to be set so that it will deliver the pallet boards from the main carrier cables onto any pair of branch carrier cables 3, and in the act of transferring the pallet boards, it will turn the same so that they will be delivered onto the said cables 3 at aright angle thereto.

one of which drivi wheels is i The transfer device comprises a multiplicity of rollers 8, 9, 9 10 and 10 The rollers 8 and'9 are journaled in parallel straight bars 11, and the rollers 9*, 10 and 10 are journaled in concentric curved bars 12, which bars 11 and 12 are suitably tied together and rigidly connected to afford a suitable roller supporting frame work. The bars 11 and 12 are pivotally connected at 13, so that the bars 11 with the rollers supported thereby may be raised and lowered,

for a purpose which will-presently appear,

while the bars 12 and the rollers supported thereby are supported in a fixed adjustment.

The rollers 8, 9, 9? and 10 are cylindrical, while the rollers 10 are tapered or conical, so that they will properly convey-the pallet board or other article on, the curved llne of the bars 12. The shafts of the rollers 10 project at their large ends and are provided With gears-'14 that mesh with intermediate gears 15 loosely journaled on the outer'face of the outer bar 12. If desired, the gears 14; may be left off from some of the rollers 10 at the delivery end of the transfer device, because the acquired momentum of the loaded' pallet board or other article being conveyed, will carry it over quite a numberof said rollers and onto the cooperating receiv connect the intermediate portions of the tie rods 18 'on opposite sides of the gears 16 and 17.

The prongs or side bars of theU-shaped frame 2O are vpivotally connected at their upper ends to the shaft 9 of the roller 9, and the ends of said shaft 9 in the construction illustrated, project for engagementwith notched upper ends of supporting posts 21. Similar supporting posts 22 support the receivingend of the frame made up in part of the bars 11. The lower portion of the frame 20carries a bearing'bracket-23, which in one side has ascable passage 24. In the lower portion of the bracket'23, a guide sheave 25 is loosely journaled, and in the upper portion-of said bracket 23, a driving sheave 26 which carries a driving sprocket 27 is loosely journaled.

the sprocket 27 and over a small sprocket 29.

A sprocket chain 28 runs over secured on the shaft 9 at one extremity of the roller 9*. Y

The numeral 30 indicates apost used to support the depending free-end of the frame 20. v a

Loosely journaled on the receiving end'of the bars 11, are idle guide sheaves 31, and on the delivery end portions of said bars, are loosely journaled similar idle guide sheaves 32.

. tion of'on'e of the carriers laterally lVhen this transfer device is properly set for delivery from the main carriers 1 to the branch carriers 3, the frame thereof will be secured by the posts suitable supporting tions of the main carriers .1 arerunover the cooperating guide sheavesj31 and under the cooperating guide sheaves 32-; the lower por- 1 will then move bracket- 23, and is passed under the driving sheave 26 and over the idle sheave 25, and by .an upward adjustment of the frame 20, the

two sheaves are caused to kinklthe said-carrier until it is given the required .drivi'ng friction. WVhen the cables 1. are then driven in the direction marked by the arrow: thereon in Fig. 2, the dri-venrollers 9, 9" and 10 will be rotatedin the direction to convey the pallet boards or other articles from the main cables onto thealined, branch or secondary on the projecting shaft It will also be noted are provided with spur gears.

15*, connect the roll-. and 10 for rotation in the same di-.. rection. Asshown in Fig. 1, metal straps 19.

the straight and tap pivotally supported 21 and 22 and any other devices; the upper por-.

through the opening 24 in the cables; By reference to Fig. 2, it will be noted that the guide sheaves 31 cause the cables 1 to deliver the pallet boards onto the upper surfaces of-the rollers 8, and thatthe.

sheaves 32 direct the cables downward under the frame and rollers of the transfer device. by reference to Fig. 1, that the roller 10 is arranged to deliver pallet boards onto the cooperating branch cables .3. 1

Obviously this transfer device may be easily moved and set for delivery at any of the several pairs. of branch cables 8. In moving the same from one position to another, it is not necessary to disturb the connections between the main cables 1 and the cooperating driving and guiding sheaves of the transfer device.

From the above description, it is evident that the transfer device is reversible,-that is, it can be turned either side up so as to be used either as a right or left hand delivery device and the pivotal connection between the frame 20 and the bars-12 of the transfer devicetis such that the frame 20 ma be swung from one side to the other 0 the transfer device, so as to always extend downward therefrom and, of course,

either position of the frame 20. I

The term cable has been used herein synonymously with belt. The term sheave has been used as an equal ofa wheel. The term parcel has been used 'toinclude any article which may be moved'by the carrier.

IVh at I claim is the drivingconnection will operate just the same in '1. In a carrier system, the combination with-a pair of cables andmeans for guiding and driving the same,0f a parcel transferring mechanism comprising Straight and curved frame-sections ivotally connected together, cylindrical frame section, tapered rollers on the curved frame section, gears connecting certain of in the samedirection, an oscillatory frame at its upper end, a pair of sheaves on the lower portion of said oscillatory frame engageable with one of said cables, connecting one of said connected rollers, substantially as 2. Ina carriersystem, the combination sheaves to said gear with a pair of cables, and means-for guiding and driving the same, of a parcel transferring mechanism comprising a frame, rollers on said frame arranged to receive the parcels from said cables, gears connecting certain of said rollers for rotation in the same direction, an oscillatory frame pivotally connected at its upper end to said roller supporting frame, a pair of sheaves on a swinging portion of said-oscillatory frame engageable in the lower portion of one of said cables, the said frame adjacent to the said ered rollers for rotation and a sprocket and chain drive.
